I. GENERAL INFORMATION
Product #1ESD Epoxy Coating System consists of
Product #899 Epoxy Primer followed with one finish coat
of Product #1ESD/Conductive Epoxy Coating. Product #1ESD/Conductive is available
in pigmented finish only. Product #1ESD Epoxy Coating System will test in the
"ESD"
range, between 1,000,000 and 1,000,000,000 ohms electrical resistance when
Product #1ESD/Conductive is applied over a non-conductive primer (or non-conductive bodycoat), and produces a 12-15 mil thick ESD floor coating system. Important
Note: Product #1ESD/Conductive when applied over a conductive primer or
conductive basecoat will test in the "conductive" range, between 25,000 and
1,000,000 ohms electrical resistance. Refer to Product #1 Conductive Coating
System for further details. A thicker system of 20-30 mils or greater can be
achieved by adding a nonconductive bodycoat, contact Epoxy.com for details.
II.
SURFACE PREPARATION
Surface Preparation is the most critical portion of any
successful resinous flooring system application. All substrates must be properly
prepared to a minimum surface profile of CSP-2 as outlined in
Epoxy.com Surface Preparation Procedures. Specific attention should be paid to the
following:
A. Concrete Placement--An efficient vapor barrier should be under
slabs on or below grade to prevent moisture migration. A moisture vapor
treatment may be necessary.
B. Curing and Finishing Techniques of the Concrete
Substrate
C. Age of Concrete D. Previous Contamination of the Substrate
E.
Present Condition of the Substrate Also, the temperature and humidity conditions
of the area to receive the flooring system should be checked. An optimum room
temperature of 75�F with a minimum slab temperature of 60�F is required for
proper cure of the resin flooring system.
III. MATERIAL QUANTITIES
A. Guideline
System Requirements for 1000 sq ft 12-15 Mils Product #1ESD Epoxy
Coating System Qty./ 1000 sq ft
1. Product #899 Epoxy Primer 4-5 gallons
2. Product #1ESD/Conductive Epoxy 5-6 gallons**
Important: Do not apply
Product #1
ESD/Conductive greater than 12 mils total thickness (in one coat) or
conductivity will decrease, possibly resulting in a zero conductivity finish.
This would then require a reapplication of Product #1ESD/Conductive.
**Note: If
specifications or facility requirements dictate the use of grounding tape, this
must be placed between two coats of Product #1 ESD/Conductive, or grounding plates
must be adhered to the surface of the final topcoat. Refer to section IV-D.
IV.
INSTALLATION
A. Product #899 Epoxy Primer
1. Mixing
a. Stir each component prior to
mixing.
b. Mix two (2) parts by volume of Part A (Resin) with one (1) part by
volume of Part B (Hardener) for three minutes with a low speed electric drill
mixing paddle.
c. If thinning is desired, add no more than one pint of xylene or
MEK per gallon of epoxy at time of mixing.
d. Do not mix more material than can
be immediately poured out and spread/backrolled in 30-40 minutes. Do not leave
mixed material in the pail for longer than 5 minutes or working time will be
significantly reduced!
2. Application
a. Pour mixed resin onto the prepared
concrete.
b. Spread with either a flat trowel or squeegee to a coverage of 200 to
275 sq ft per gallon.
c. Back roll with a short nap roller.
d. Allow primer to
cure 8-12 hours (at 75 degrees F) prior to topcoating. A fast cure formulation
is available to reduce re-coat window to 4-6 hours. If primer is to be allowed
to sit for longer than 24 hours, sand primer before topcoating.
B.
Product #1ESD/Conductive Topcoat
Note: This system must be applied with a smooth
finish texture or very minimal texture to ensure proper contact of the test
apparatus with the surface of the coating. IMPORTANT: Do not apply
Product #1ESD/Conductive greater than 12 mils total thickness (in one coat) or
conductivity will decrease, possibly resulting in a zero conductivity finish.
This would then require a reapplication of Product #1ESD/Conductive.
1. Mixing
Product #1ESD/Conductive
a. Stir each component prior to mixing.
b. Mix three (3)
parts by volume of Part A (Base) with one (1) part by volume of Part B
(Hardener) for three minutes with a low speed electric drill mixing paddle.
c.
Mix only the amount of material that can be immediately poured out.
2.
Application a. Immediately pour mixed material onto floor in strips and spread
at a rate of 160- 200 ft� per gallon with a squeegee. b. Back roll immediately
with a short to medium nap roller. Do not backroll excessively.
3. Allow to cure
overnight or a minimum of 12 to 16 hours at 75 degrees F.
4. Do not open to light foot traffic for 24 hours, light to medium duty
wheeled traffic for 48-72 hours at 75 degrees F. Full chemical cure is
achieved in 5 to 7 days at 75 degrees F.
5. After 72 hour cures of topcoat, test
floor with floor surface ohm meter, confirm that conductivity meets
requirements. Flooring contractor or owner�s agent is responsible for testing
floor. Final conductivity testing requires 72 hours cure time to obtain final
readings. Testing performed prior to 72 hours cure time will initially yield
higher test results (higher ohms), which will decrease as cure time progresses
to 72 hours.
C. Testing
1. Testing should be performed after 72 hours to confirm
proper conductivity range.
2. Test multiple random areas to confirm a
conductivity range of 1,000,000 to 1,000,000,000 ohms. Consult with
Epoxy.com
Technical Service if any areas do not test properly.
D. Installation of
Grounding Tape, Grounding Plates and Connection to Building Ground Points
Note:
May be optional depending on project and/or building owner's requirements
A high degree of ESD control can be achieved without direct connection
to an earth grounding point, particularly for floor installations bonded
directly to concrete. However, building owners, project specifications
or critical applications may dictate that the ESD flooring be connected
to properly prepared grounding points using copper tape, plates and/or
wire. Metal floor joints, metal equipment bases and steel columns/posts
may be used if they have been electrically tested to confirm permanent
continuity with an earth ground. This should be confirmed by the
building owner's electrician. Unless otherwise specified, a general rule
of thumb is one grounding point per every 1000 square feet of flooring.
Metal structures used as grounding points must be cleaned, sanded or
lightly abraded with a grinder to remove all insulative coatings, rust
and dirt. Approximately 1/4" height by 3" width of surface preparation will be
necessary to create a grounding point.
Copper tape with conductive adhesive can
be used to connect the flooring system to grounding points, bridging over
exposed joints around columns or connecting different concrete slabs separated
by exposed joints. Copper tape may not maintain long-term integrity over
expansion joints that experience significant movement. Suppliers of copper tape
and/or grounding plates: McMaster-Carr (www.mcmaster.com, part #76555A642, Ground Zero
Electrostatics (www.gndzero.com) for various sizes of tape, grounding plates and
lead wires.
1. A minimum 4" length of copper tape is adhered between two coats
of Product #1 ESD/Conductive, prior to final topcoat installation, with the
remainder length allowed to run up the wall to an electrical outlet where it can
be attached by an electrician. The connection is made to the green wire or
grounding portion of the electrical outlet. For metal structures such as
columns, attach tape to prepared surface by drilling hole into steel and
securing tape with machine screw and washer.
2. Alternate method using copper or
other conductive metal plate: In addition to installing copper tape as outlined
above, adhere plate to surface of cured Product #1 ESD/Conductive topcoat. Use
plate with conductive adhesive backing. Attach copper wire (#10 or #12 gauge) to
plate and electrical outlet ground or secure to hole in steel structure with
machine screw and washer. Plates purchased from Ground Zero have lead wires
attached to plate.
3. Alternate method for attaching to ground point inside
drywall: Connect #10 or #12 wire from any convenient ground point and drop down
to floor/wall junction, with wire brought underneath wall via a small hole cut
into drywall or chip out hole in concrete floor. The copper wire is intertwined
or soldered to the copper tape or plate. If using tape, it can be pushed into
the wall
